Beekeeping is full of new terms and acronyms. Here are a few definitions. This isn't a complete list by any means- I've just made entries when I find myself using a specialized term on one of our pages that I think needs clarification.
Out-Apiary: Somewhere you put your bees other than at your In-Apiary
NUC: A NUC or "nucleus" hive is a small, usually 4 or 5 frame box but occassionally as small as 2 frames. Used to make splits of existing hives for increase or sale, or to nurse along a weak or ailing colony.
SBB: Acronym for Screened Bottom Board- either a bottom board with an integral screen or an add-on for a conventional bottom board.
